TIPULA FALLAX AND OTHERS. 



By R. W. DoANE, 

 Stanford University, California. 



For sometime I have had in my possession a number of species 

 of Tipula with wing markings similar to T. fallax, hebes and grata. 

 T. hebes may at once be distinguished by the yellow antennae with 

 the black rings at the base of each segment beyond the third and 

 by the first posterior cell being black only in the base. All attempts 

 to separate the others on the basis of wing markings or other mark- 

 ings on the body have proved futile. An examination of the hypo- 

 pygium shows that eight different species, the three just mentioned 

 and five new ones, are represented in the lot. 



T. fallax is represented in my collection by specimens from 



Fig. 1. ]Ving of Tipitla fallax Lw. 



Stanford University and vicinity; Keyport, Washington; Sitka, 

 Alaska. A single female from Oak Creek Canon, Ariz., is also 

 placed here but it is not impossible to definitely place the female 

 without the males. 



Another group from Keyport and Olympia, Washington, is 

 represented by ten males and possibly two females. The mark- 

 ings of the wings and body are similar in almost every respect 

 except that as a rule, but not always, the markings are a little 

 more intense. I have always confused this species with T. fallax 

 and Snodgrass, in his article on the "Hypopygium of the Tipu- 

 ladse," Trans. Amer. Ent. Soc, Vol. XXX, No. 3, relying on my 

 identification, figures this species under that name. A descrij)- 

 tion of the species follows :
